A UNIQUE SOUTHERN SPECIMEN 247 



which renders it markedly different from any other form 

 of eurytus yet known. It seems to combine the features 

 of the western eurytus male with the imitator of Natal. 

 The subapical orange area of the fore wing is small and 

 narrow, as is the corresponding pale area of imitator^ 

 and the inner marginal area on the fore wing is like that 

 of eurytus. The hind wings have a very large orange 

 area with only a narrow black border, as in the western 

 eurytus, but at the base they show the very large purplish 

 brown aposeme extending along the costal margin to 

 the tip as in imitator. This most interesting specimen 

 is a male, and one awaits the discovery of its female 

 with enthusiasm : probably it will be black and white. 

 It presumably mimics a local form of Planema aganice 

 which has yet to be discovered. 



In 1904, S. A, Neave described four new Pseudacraeas 

 from Uganda, which are now known to be all forms of 

 eurytus, using the name in its wide sense. The form 

 hobleyi was the first to be named, and the others make 

 with it a group inhabiting Uganda, although some at 

 least extend their range out to the West Coast. Hobleyi 

 is a male form only, mimicking the male of Planema 

 macarista.^ On a ground of blackish brown it has a bright 

 orange bar bent at an angle, crossing the fore wing, and 

 a white bar crossing the middle of the hind wing. This 

 latter bar, however, as in the model macarista^ is often 

 bordered with orange-brown and, in examples brought 

 by Neave from Western Uganda, becomes wholly orange. 

 This form appropriately mimics the local form of Planema, 

 in which the white bar of macarista is replaced by orange. 

 This is Planema pseudeuryta, very closely alHed to 

 macarista. The form hobleyi has a basal aposeme on 

 the under surface of the hind wings, but this differs 

 sUghtly from that of imitator, being more concentrated 

 into a basal triangle, and of a more reddish and less
